[idea] Configurable in-app toast duration + queue-style open_notification_target

[liwuhou]

idea / problem

I’m using ui.toast.delivery = "herdr" because it’s the only notification mode that can take me to the exact workspace/tab/pane.

What feels awkward today is:

1. the in-app toast disappears too fast
2. open_notification_target only works for the currently visible notification target

A lot of the time I notice the toast, move to click it, and it’s already gone. And if several background notifications arrive
close together, there isn’t a good keyboard-first way to work through them in order.

requested change

I’d like Herdr to support two things:

1. configurable in-app toast duration
2. queue-style open_notification_target navigation

For the toast duration, something like this would help:

[ui.toast.herdr]
position = "bottom-left"
duration_seconds = 10

A sticky mode would also be useful, so the toast could stay until clicked or dismissed.

For open_notification_target, I’d like it to walk through retained notification targets in the order they appeared.

Example:

1. Agent A finished
2. Agent B needs input
3. Agent C finished

Then repeated open_notification_target presses would go:

• first press → A
• second press → B
• third press → C

Exact config or action naming is not important. The main request is:

• let users keep in-app toasts visible longer
• let keyboard navigation step through recent notification targets sequentially

why you want this

delivery = "herdr" is much better than system notifications because it can jump to the right pane, but the current toast
lifetime is short and there’s no good sequential way to triage multiple background notifications.

This would make multi-agent workflows much smoother, especially when several agents finish or block around the same time.

I support this. System notification (macos in my case) doesn't allow customizations so it uses a generic system, so herdr notification is the best alternative for me, but it needs more customization options
